The sendback is a minimum amount of ADA that needs to be sent with every transaction that contains an asset. For an easier price calculation, you can set the sendback to 2ADA for each NFT, or 2 ADA for every 5 NFTs that were sent in one transaction. For reduced costs, please select "MinUtxo", this will calculate the sendback of each single transaction depending on the metadata size and token amount.
If you want to block a certain amount of random NFTs from being sold, please specify the amount here in your project settings and click on save.
Depending on how you plan to set up the sales, disable random sales or disable specific sales with the buttons in the lower corner or the tab. 'Disable random sales' will only allow specific payment links and 'Disable Specific sales' will only allow random sales via NMKR Pay or the Pay-In Address. Further helpful Information is Security Practices and Deal with Bots.
